Well after about 5 hrs on my bike from this mod - I can say with 100% certainty this is the best bang for the buck I have every spent on modding my bikes. $100.00 and my bike absolutely rips....I let a buddy of mine ride it yesterday. He is a A-Rider that is going Pro this year. He is and has been on CRFs for the past few seasons....his response after riding my bike...the throttle response and power low to mid transition flat out blows his CRF away. Although his CRF has more on top, which is the case for 06/07 CRFs he is flat out amazed by response from starts and out of corners..he did prefer my suspension to his, but that is another story...he is pulling his carb out tomorrow to ship to ZipTy...
the facts -
Carb is completely checked, cleaned
AC pump is wired - correctly no issue of ever binding
a emulsion tube is added -
Fuel - Zipty said pump gas is fine but recommends VP C12 and prem pump 50/50 blend - this is what I am using
I have aftermkt WB Alum Pro2 complete system so power is better everywhere
no more popping period end..absolutely zero hesitation on twisting the throttle
jetting is stock 168mj/48pj - 06 stock needle 4th clip - I will swap out stock needle for NFLR this week and see what results this gives
power is increased - to me at all rpm ranges..it is night and day different than my 06 was stock..
bike starts on first kick everytime
This made me learn Carb dynamics much more....as well as removing/reinstalling carb is a breeze now...just don't dissconnect the TPS
on the carb like I did...big no no
and no Zipty is not paying me....
the bad news....my lower back is killing me today...it sux getting old
